Biologic information feedback system based on virtual reality

Abstract

The invention discloses a biological information feedback system based on virtual reality, which comprises an acquisition system S1 and a virtual reality feedback system S2; the acquisition system S1 comprises a plurality of scalp electrodes, an electroencephalogram (EEG) signal extraction module and an EEG signal processing module; and the virtual reality feedback system S2 comprises a management module, a database, a feedback training module, a display module, an off-line analysis module, a communication logic module and an EEG secondary processing module. The biological information feedback system of the invention accurately collects the biological electric signals, processes and extracts the pure EEG signals, processes signal characteristics, and compares with the database and analyzes to obtain an accuracy pressure level; an intervention system can be configured for different diseases to achieve a targeted intervention system; real-time operation realizes a real-time feedback system, so that the current state of a subject can be visually observed, thus achieving self-training and adjustment; and good virtual reality system and the new design of interactive scenes and interactive means can enhance the sense of interaction and immersion and operability.

Description

technical field [0001] The invention relates to a biological information feedback system, in particular to a biological information feedback system based on virtual reality, which belongs to the technical field of medical instruments. Background technique [0002] When the brain nerves are active, there will be weak electric field fluctuations. When tens of thousands of nerves are active at the same time, the electric field will produce rhythmic fluctuations. This fluctuation can be measured from the scalp, which is the brain wave. Brain wave has the following characteristics: it is a bioelectrical signal spontaneously generated by the central nervous system; it is a random signal with non-stationary and non-Gaussian characteristics; it can reflect the state and changes of the nervous system. Therefore, by collecting and analyzing brain waves, it is possible to monitor people's physiological and psychological states. [0003] Non-invasive EEG acquisition technology is rela...
